SOIL SAMPLING DEVICE AND SOIL SAMPLING METHOD
To provide a soil sampling device and a soil sampling method that can collect a soil sample with less disturbance by, for example, utilizing a Swedish weight sounding test device.SOLUTION: The soil sampling device includes an outer tube 1, an inner tube 2, a screw shaft 4, a bearing 5, a push-in base 6, a piston 7, a rib 8, and a guide 9. The screw shaft 4 is provided in the inner tube 2 so that their axes O1 are arranged coaxially. The bearing 5 is provided integrally on a rear end side of the outer tube 1 and axially supports the screw shaft 4 about the axis O1 rotatably. The push-in base 6 is provided integrally on a rear end side of the inner tube 2 and rotates the screw shaft 4 about the axis O1 normally and reversely as well as advancing and retracting in the direction of the axis O1. The piston 7 is provided by being connected to the tip of the screw shaft 4, and is arranged so as to close the opening of the inner tube 2 on the tip side in the state where the inner tube 2 is retracted. The rib 8 protrudes outside from an outer surface of the outer tube 1 and prevents the outer tube 1 from co-rotating by biting into the ground. The guide 9 guides the push-in base 6 and the inner tube 2 in the direction of the axis O1 to make them advance and retract.SELECTED DRAWING: Figure 1
【課題】スウェーデン式サウンディング試験装置を利用するなどして乱れの少ない土試料を採取することを可能にする土試料採取装置及び土試料採取方法を提供する。【解決手段】外管1と、内管2と、内管2の内部に互いの軸線O1を同軸上に配して設けられるねじ軸4と、外管1の後端側に一体に設けられ、ねじ軸4を軸線O1周りに回転可能に軸支する軸受5と、内管2の後端側に一体設けられ、ねじ軸4を軸線O1周りに正逆回転させるとともに軸線O1方向に進退する押し込み台6と、ねじ軸4の先端に接続して設けられ、内管2を退避させた状態で内管2の先端側の開口を閉塞させるように配設されるピストン7と、外管1の外面から外側に突設され、地盤に食い込んで外管1の供回りを防止するリブ8と、押し込み台6及び内管2を軸線O1方向に案内して進退させるガイド9とを備える。【選択図】図1
